I took two of my grandchildren who were visiting from out of town to eat at Steak 'n Shake, upon their request. As we waited to be seated, I noticed the floors were very dirty, especially under the booths/tables. I also noticed a family who came in, were seated, then in a few moments, got up to leave the restaurant. When we were seated, I mentioned to the server that there was food/trash under our table. He proceeded to take our order, served our food, but, no attention was ever given to clean up under our table/feet. This same condition was seen throughout the restaurant. I didn't want to make a scene with my grandchildren, so, when we got up to leave, I mentioned the dirty conditions to the manager. He said that they were very busy, but, they weren't. I couldn't help but wonder what the kitchen looked like. I haven't returned there again.
